i recently bought an iiyama monitor. GB2470HSU. gmaster red eagle something or other. i plugged it into my laptop as a second screen at first and set it as the main monitor. audio started playing from monitor speakers. superb. i plugged in my headset (headphone + mic combo) to the audio jack port at the back of said monitor. it worked. outstanding. after a while the new monitor screen went grey static-y and the audio switched back to the laptop by itself after the monitor returned to normal. not great. i tried to make it work (made sure it was still set as the main monitor, updated drivers, unplugged and plugged in the audio jack, hdmi cable, monitor, restarted laptop bajillion times) . it didnt work. i plugged in my headset to the laptop and i could hear again. not what i wanted but i'd live. recently borrowed old pc from a friend. "separate headphone and microphone jacks"-old. since i only have one jack on the headset, i now have a choice of either hearing things or yapping to people, but never both. misery. monitor isnt detecting headset audio jack. or maybe its the computer itself. did the whole "fix it" spiel again, but alas, to no avail. realtek audio manager only shows pc audio and mic ports. the simple monitor audio port drowns in circles of green and pink. please help me
